SGP30 Air Quality Sensor Breakout
Measure indoor air quality—total volatile organic compounds (TVOC) and equivalent CO2 (eCO2)—with this digital sensor for Raspberry Pi and Arduino.
The SGP30 sensor measures two different types of gases: volatile organic compounds (like hydrocarbons) and equivalent carbon dioxide (H2 level is used as a proxy for this). The sensor does some nifty real-time baseline compensation to give you the most accurate readings, with just a 10-15% margin of error and minimal drift through time.
It's also compatible with Pimoroni's fancy Breakout Garden, where using breakouts is as easy just popping it into one of the six slots and starting to grow your project, create, and code.
Important! The sensor has a PTFE membrane over it (it looks like a slightly translucent white film). Do not peel it off! This is a gas-permeable membrane that is required for the sensor to function as intended.

- Reverse polarity protection
- Raspberry Pi-compatible pinout (pins 1, 3, 5, 7, 9)
- Compatible with Arduino
- Compatible with Raspberry Pi (Python library)
- Compatible with Raspberry Pi Pico (C++/MicroPython libraries)
- SGP30 breakout
- 1x5 male header
- 1x5 female right angle header
We've designed this breakout board so that you can solder on the piece of right angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 7, 9).
Here is a a Python library that you can use to read data from your SGP30 breakout, and provided an example of how to use the library.
You can also use this breakout with Raspberry Pi Pico and other RP2040 boards, using C++ or Pirate brand MicroPython.
- When you first set the sensor running, it takes some time to warm up (up to a minute) before returning readings
- Dimensions: 19x19x3mm (LxWxH)
